Firearms

Firearms and ammunition are both polished in Mass Finishing, Inc. machines.

The Firearm industry uses MFI polishing machines to finish the small moving parts that make rifles and handguns fire, such as the springs and trigger mechanisms. By tumbling these parts inside our HZ-Series centrifugal barrel finishing machines, the firearm performs at its best and is less prone to jamming.

Ammunition makers also rely on tumbling and vibratory machines from Mass Finishing, Inc. to polish the inside and outside of bullet and shell casings. HZ Series machines can finish hundreds of casings at once dramatically improving efficiency.
